77115601 ÷ 612 
Our goal is to divide 77115601 by 612.

Advancing to step 1:
612 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 612

Let's proceed to step 2:
The number 612 fits into 77 0 times, leaving a remainder of 77.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (1) from the dividend, attach it to 77 and continue: 771 / 612

On to step 3:
The number 612 fits into 771 1 times, leaving a remainder of 159.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 612 from 771 leaves us with 159.
Bring next digit (1) of the dividend behind the 159 and repeat the process: 1591 / 612

On to step 4:
612 goes into 1591 2 times with a remainder of 367.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 1224 from 1591 and we're left with 367.
Take the next digit (5) from the dividend and append it to 367, then repeat: 3675 / 612

On to step 5:
3675 divided by 612 is 6 with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
Deduct 3672 from 3675 and we're left with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 612

Let's proceed to step 6:
612 goes into 36 0 times with a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 1260.0
Subtract 0 from 36 to get 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 612

On to step 7:
If we divide 360 by 612, we get 0 and a remainder of 360.
The next digit of our result is 0. 
Result so far: 12600.0
If we take 0 away from 360, we end up with 360.
Fetch the next digit (1) from the dividend, attach it to 360 and continue: 3601 / 612

Let's proceed to step 8:
The number 612 fits into 3601 5 times, leaving a remainder of 541.
The number 5 becomes the next digit in our result. 
Result so far: 126005.0
The remainder is 541 after subtracting 3060 from 3601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Moving on to step 9:
612 goes into 5410 8 times with a remainder of 514.
Put 8 as the next digit of the answer. 
Result so far: 126005.8
If we take 4896 away from 5410, we end up with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 10:
612 can be fit into 5140 8 times, resulting in a remainder of 244.
The number 8 becomes the next digit in our result. 
Result so far: 126005.88
Subtracting 4896 from 5140 leaves us with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

The quotient of the division is 126005.88, and the remainder is 0.244.
